TRUSS.

SPECIFICATION forming part of Letters Patent No. 480,77 5, dated August16, 1892.

Application filed October 14, 1891- .To all whom it may concern.-

Be it known that I, JOHN ALBERT MARVIN, acitizen of the United States,residing at Lans1ng,in the county of Ingham and State of M1chigan,haveinvented certain new and useful Improvements in Trusses; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to trusses, and has for its object the improvementin the manno};i of supporting and adjusting the trusspa My improvementsare especially adapted to inguinal and femoral trusses, although part ofthem may be employed with other forms.

In many forms of trusses the pad is secured to one or more straps thatin turn are secured to a single body strap or belt, or the pad issecured directly to the body -belt-. The difficulty experienced in suchcases is that the belt slips up or down, especially down, with thosepersons who have hardly any or slightly-projecting hips, or it becomesdisarranged by the motion of the body or legs, thus disturbingconstantly the position of the pad and causing great annoyance and pain.To correct this and other difficulties, I employ the combination andarrangement of belt, pads, and straps, as hereinafter described andclaimed.

My invention is illustrated in the accompanying drawings, in whichFigure 1 is afront perspective view, and Fig. 2 a back view.

Referring to the drawings, A is a broad flexible back pad composedpreferably of leather stitched to webbing and lined with silk. Thisleather piece is arranged vertically, and is strengthened and stiffenedby a central longitudinal piece a of flexible fabric, by a toplongitudinal piece a and also by the bottom body-belt E. The piece A isalso strengthened and stiffened by a central line of stitching.

To the top back portion of the back pad A and on its opposite sides, issecurely pivoted by means of rivets, two adjustable straps B B.

These straps are passed around the body, and

Serial No. 408,677. (No model.)

to their front ends are secured by means of loophooks a two V supportingstraps O, which extend down from the straps B B and carry and directlysupport a truss-pad D; but, if preferred, the straps B B may be extendeddirectly down to and be connected to the truss-pad in the same manner asare the straps C.

E is a single body-belt secured to the back pad A below the upper strapsB and sepaarated therefrom by a considerable space. This lower strap Eis passed directly around the body below the hips and its ends united infront by a loop-buckle b.

F is a perineal band, one end of which is secured by means of ascrew-pivot 12 over the ends of the straps O to the truss-pad D, and theopposite end of which is pivoted and permanently secured to a slidingleather loop G on one of the lower straps B. The straps B are passednearly around the body and supported in position over the hips. noticedthat the whole bearing from which the truss-pad is mainly supported isthus thrown on the pad on the back through the upper straps B, which aremostly above the hips,

It will be and by which arrangement the truss-pad is held in place andis not permitted to slide up and down .with the movement of the body andthe body-belt. This arrangement, too, combines a direct body-belt andabdominal support with a belt carrying a truss-pad, each performing itsseparate functions without interference, and yet both united to a commonfirm comfortable back support.

My improvements are as well adapted to be used with doubletruss-pads byduplicating the straps by which they are connected to the lowerabdominal belt, and in such case the advantages of my arrangement ingiving support to the pad directly from the back piece will be stillmore apparent.

What I claim is- In combination with a truss-pad, a central backflexible support or bearing, a single lower body-belt rigidly secured tosaid hearing and passed entirely around the lower part of the abdomen,unconnected with thetrusspad, with its two ends hooked in front, two

upper body-straps secured to the upper part of said back support and tothe truss-pad, and a, perineal strap, one end movably secured to saidlower body-belt and the opposite end to the truss-pad, the truss-padthus held below the body-belt, substantially as described.

In testim ony whereof I affix my signature in presence of two witnesses.

JOHN ALBERT MARVIN.
